id summary reporter owner description type status component version resolution keywords cc guest host 8057 First mouse click in virtual screen interpreted as drag Matthew Francis "With an OSX host and Linux (Fedora 14) guest with guest additions installed, a mouse click into the guest that also transfers focus to the running VirtualBox host window causes an undesired drag from the previous mouse position within the guest (before host focus moved). This can have a number of undesirable effects on the guest depending on what exactly is on screen at the time. Steps to reproduce: 1. Install Fedora 14 and guest additions on an OSX host, and run in single-window mode with mouse integration enabled 2. With a clean F14 desktop (no windows open), focus another host (OSX) window 3. Left-click and hold at any position on the F14 desktop. A selection rectangle should be visible from the last position of the mouse within the guest before host focus was lost (the bug occurs even without holding, but the desktop selection rectangle shows what is happening clearly) Expected behaviour: The click (or drag) should be experienced by the guest as starting from the position of the click into the guest desktop, not the position of the mouse prior to loss of host focus " defect reopened guest additions VirtualBox 4.0.0 Linux Mac OS X
